Development with a build-time transpiler

Instead of writing scripts in the current version of JavaScript, ECMAScript 5, we can also write scripts in ECMAScript 6+ using Typescript and Transpile them into ECMAScript 5. Then, Deploy the transpiled script to the Server, and the Browser Request will be served with the Transpiled script, which is ECMAScript 5, that is to be executed on the client side. The benefit of this is that we can use the new features of the latest version of JavaScript or ECMAScript.
